How to fix?

Upgrade Wolfi thingsboard to version 4.3.1.1-r5 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream thingsboard package and not the thingsboard package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

A WebFlux server application that processes multipart requests creates temp files for parts larger than 10 K. Under some circumstances, temp files may remain not deleted after the request is fully processed. This allows an attacker to consume available disk space.

Older, unsupported versions are also affected.
